CAUTION!
If faults cannot be eliminated by means of the measures listed above, shut down the pressure transmitter
immediately, and ensure that pressure and/or signal are no longer present, and secure the instrument from
being put back into operation inadvertently. In this case, contact the manufacturer. If a return is needed,
please follow the instructions given in chapter 10.2 "Return".

10. Dismounting, return and disposal

WARNING!
Residual media in dismounted pressure transmitters can result in a risk to persons, the environment and
equipment. Take sufficient precautionary measures.
10.1 Dismounting
WARNING!
Risk of burns!
Let the instrument cool down sufficiently before dismounting!
During dismounting there is a risk of dangerously hot pressure media escaping.
When removing the instrument, the force required to do this must not be applied through the case or the cap ring, but
only through the spanner flats provided for this purpose and using a suitable tool (see chapter 6.1.2 "Installing the
instrument").
When there is a cooling element, the lower hexagon should be used for unscrewing (see chapter 6.1.2 "Installing the
instrument")
Only disconnect the pressure transmitter once the system has been depressurised!
